Heaven forbid you have a not-too-common disorder, illness, or mental condition. The medical system is not a very open-minded organization as a whole.

The doctor I used to work for poo-pooed chiropractors. It is only recently that chiros became covered by insurance.

My wife has fibromyalgia. Most docs will tell you it doesn’t exist.
Won’t my wife be surprised?
BUT WAIT!
There is now a medicine approved for treatment of fibromyalgia.
Therefore it exists.
Perhaps this is quantum physics: the discovery of a drug called the disorder into existence.

I can distill it thusly: if they can’t write a prescription for it, it doesn’t exist.

Long before we had Big Pharma, the Chinese were sticking needles into people and helping or curing them. Now acupuncture and `folk remedies’ are passe’, regardless of efficacy. [to be fair, my insurance covers needles]

And then there’s mental health.
My wife has a diagnosis that `doesn’t exist’. The doc will tell you to your face that it doesn’t. Let’s face it - everybody’s just depressed or bipolar anyway - give them lots of meds and send them on their way.
